About Romain

Need a Tech Lead who understands business stakes as much as technical complexity?

With 25 years of experience, I've evolved from the industrial rigor of large groups to the agility of SMEs, working with complete autonomy or in agile mode within international teams.

I'm not just a developer: I'm a "Product Engineer".
I design robust architectures and implement them while focusing on the final user experience (UI/UX).

What I bring to your project:

Seniority & Architecture:Ability to audit, refactor, or design complex systems (Hexagonal Architecture, Clean Code).

Dual Dev / UX Skill:I bridge the gap between technology and product. Creation of Design Systems, wireframing, and pixel-perfect integration.

Technical Leadership:Experienced in mentoring junior teams, establishing best practices (Code Review, CI/CD), and securing deliveries. Also capable of working alone, with complete autonomy, on the entire product lifecycle.

Pragmatism:A results-oriented culture, robust and scalable, but without over-engineering ((Keep it simple!) Client-focused approach.

Preferred Technical Stack:

Front-End:Angular, React, TypeScript.

Back-End:C# .NET Core, Node.js, REST API.

Data:SQL Server, MySql, MariaDB, NoSQL databases.

Organization & Mobility:

Based in Occitanie, in Rodez in Aveyron, I have been working remotely for years.
However, I remain mobile occasionally to maintain human connection:

Occitanie (Toulouse/Montpellier):Mobile on-site 1 day/week (Personal vehicle).

Paris / Île-de-France:Thanks to the daily flight connection (Rodez-Orly), I am available on-site for the day (or longer) for key stages (Launches, Workshops, Steering Committees).

Note:Primarily remote work / Travel expenses to be covered by the client.

Available to discuss your current technical challenges.
